The structures in the electronenergyloss spectra for the longlived 3p, 3d, and 4s core excitations in clean zirconium are accounted for by the unoccupied density of states. Transitions to final states with different angular momenta are observed. The shortlived 4p excitations can only be understood in terms of an atomic theory given by Fano that treats excitation...

The np coreloss spectra and the associated deexcitation processes for the transition metals V (n=3), Zr, Nb, Mo (n=4), and Ta (n=5) have been studied in lowenergy electron scattering experiments in order to investigate the dependence of their nature on the principle quantum number n. For the metals with n=3 and n=4, the measurements are accounted for in...

Structures in the electronenergyloss spectrum up to 30 eV above the L2,3 edge of clean silicon, excited with high and lowenergy electrons, are found to be in good agreement with a multiplescattering calculation of the empty density of states of a tetrahedral cluster of 17 silicon atoms. The relaxation of the excited atom is investigated by means of the emission...

Characteristic electronic transitions and the associated fine structure in the nearedge region are investigated with electronenergyloss spectroscopy for the copper L and M edges. In a singleparticle scattering picture this fine structure represents the unoccupied density of states selected by the matrix elements. However, electronic processes can often complicate this simple...

Electronic transitions near the 3s edge of copper are investigated with electronenergyloss spectroscopy and compared with realspace multiplescattering calculations. Calculating the generalized oscillator strength illustrates the importance of dipoleforbidden transitions in the nearedge region and shows for the first time the feasibility of making detailed comparisons between theory...
